INSTALLATION AND OPERATION INSTRUCTIONS
INFRARED RADIANT PATIO HEATER
OWNER / INSTALLER: For your safety this manual must be carefully and thoroughly read and understood before
installing, operating or servicing this heater. This heater is intended for use with either Natural Gas or Propane
Gas. It must be installed by a qualified service person or a licensed contractor in accordance with state and local
codes.
: Improper installation, adjustment, alteration, service, or maintenance can cause property
damage, injury or death. Read the installation, operation and maintenance instructions thoroughly before
installing or servicing this heater. For assistance or additional information, consult a qualified installer, service
agency or the gas supplier.
For Indoor Installations INSPECT all combustion air openings into the building and, if necessary, clear if they
become blocked.
FOR YOUR SAFETY: If this heater is installed indoors, it must be in a sufficiently ventilated space. Exhaust fans
MUST be operating on an appropriate cycle when heaters are operating to avoid a high concentration of carbon
monoxide. When installed in insufficient ventilated spaces this heater may give off carbon monoxide, an
odorless and poisonous gas. CARBON MONOXIDE POISONING MAY LEAD TO DEATH. Early signs of carbon
monoxide poisoning resemble the flue with headaches, dizziness and nausea. If you experience these signs, GET
FRESH AIR IMMEDIATELY! Have the heaters serviced as soon as possible and check the ventilation into the
building.
INSTALLER: This manual is the property of the owner. Please present this manual to the owner when you leave
the job site.
IF YOU SMELL GAS:
1. Shut off gas to the appliance.
2. Extinguish any open flame.
3. If odor continues, keep away from the
appliance and immediately call your gas
supplier.
!IMPORTANT: SAVE THIS MANUAL FOR FUTURE REFERENCE.
